Rays’ outfielder Steven Souza Jr. will be undergoing tests on his left hip on Monday, according to the Tampa Bay Times’ Marc Topkin. If he needs surgery, it would spell the end of the season for the 27-year-old, who has been battling hip pain on and off for the last three months. It’s the latest in a long string of injuries plaguing major league rosters this weekend, from Jacob deGrom‘s possible elbow surgery to Carlos Carrasco‘s broken hand and Keon Broxton‘s fractured wrist.

The Rays rank 16th among clubs in time lost to injuries this season, with 942 days spread over 53 injuries (via Baseball Injury Consultants). In the last month, they’ve already lost shortstop Matt Duffy to a left Achilles heel injury and first baseman Logan Morrison to a left torn wrist sheath.

Souza injured his hip in June, when he experienced some soreness after diving for a ball in an 8-7 win over the Mariners. He returned after a 17-game hiatus and has played consistently from early July through September, albeit not without occasional discomfort. The surgery, if necessary, would be more of a preventative measure for the outfielder, who told the Times that the pain was caused by pinching due to irregular bone growth:

We’ve known it the whole year. Sometimes it never inflames back up and sometimes it comes right back. And that’s kind of what the doctor said to me when I was there (in June), eventually is this is something that we need to deal with, just when is the question.

With the Rays already eliminated from playoff contention, now appears to be the optimal time to address the issue. Souza is batting .244/.302/.408 with 17 home runs in his second season with the Rays and is slated to start with the team on Sunday against the Orioles.

Buchholz, 33, was acquired by the Phillies from the Red Sox in December 2016, but he made only two starts before an MRI revealed he had a partial tear of his right flexor pronator mass. He underwent surgery in April and missed the rest of the season.
